Can't tween door CFrame

Help and Feedback Scripting Support

1.I want to make a door that closes and opens when the player clicks on it.

2.I tried to tween the CFrame of the door to the CFrames of 2 other parts BUT when I try to open the door I get the following error in the output : “Unable to cast value to Object”.

3.I tried multiple ways of making the door open and close but this one is the closest I got to working.

Down below is the part of the script that doesn’t seem to work.

local door = script.Parent --the door
local DoorCF = door.CFrame
local ClosedP = script.Parent.Parent.ClosedPart
local OpenP = script.Parent.Parent.OpenPart

local CanBeClicked = true
local IsOpen = false

--tween stuff
local tweenS = game:GetService("TweenService")
local TweenInfoStuff = TweenInfo.new(1.5, Enum.EasingStyle.Sine,Enum.EasingDirection.Out,0,false,0.15)

local CloseGoal = {}
CloseGoal.CFrame = ClosedP.CFrame

local OpenGoal = {}
OpenGoal.CFrame = OpenP.CFrame

local CloseTween = tweenS:Create(DoorCF,TweenInfoStuff, CloseGoal) --error happens here
local OpenTween = tweenS:Create(DoorCF,TweenInfoStuff, OpenGoal)

Im not that good at scripting so the script may be a little messy.

you must do

local CloseGoal = {CFrame = ClosedP.CFrame}
local OpenGoal = {CFrame = OpenP.CFrame}
3 
local T = game:GetService('TweenService')
function tween(o,t,l,s,d)
	s = s or Enum.EasingStyle.Linear
	d = d or Enum.EasingDirection.InOut
	local i = TweenInfo.new(l,s,d)
	return T:Create(o,i,t)
end

local door = script.Parent --the door
local DoorCF = door
local ClosedP = script.Parent.Parent:WaitForChild('ClosedPart')
local OpenP = script.Parent.Parent:WaitForChild('OpenPart')

local CanBeClicked = true
local IsOpen = false

local CloseTween = tween(DoorCF,{CFrame=ClosedP.CFrame},1.5)
local OpenTween = tween(DoorCF,{CFrame=OpenP.CFrame},1.5)

Just as an optional thing, I would recommend using a custom tween function like the one I’ve provided at the top of the script. If you’re making tweens a lot, this function makes it a lot easier to use and remember (plus also has defaults).

Arguments for that specific function are as follows:
object/instance, array of properties/goals, length of time, easing style (default is Linear), and easing direction (default is InOut).

It doesn’t work.

i misput the OpenGoal Table inside of it, fixed.

I tried your script but it still gives the same error here:

	local i = TweenInfo.new(l,s,d)
	return T:Create(o,i,t) --error happens here.
end

The first argument to TweenService:Create() is not a CFrame but the instance the tween must be created for so you need to pass the door instance as first parameter and you also need to call :Play() to run the tween

You can learn more about TweenService here: TweenService

Thanks the script works just like I wanted it to work!

Ah, I didn’t notice that DoorCF you had as a CFrame instead of the instance. Should be fixed now. I know you’ve got it solved now, but I’d still recommend using a function like that in the future to save time. :+1:
